Abstract: A system is configured to store a relationship data set of a plurality of diagnostic estimators and a plurality of failure modes, each failure mode represents a type of failure that can occur with a sensor or a vehicle component of a vehicle system, each diagnostic estimator is associated with a respective subset of the failure modes, each subset defines a control space within the vehicle system that contains at least one of (i) one or more sensors or (ii) one or more vehicle components. The system is configured to store a healthy diagnostic vector regarding nominal operational parameters of the vehicle system; acquire diagnostic information regarding current operational parameters of the vehicle system to generate an error diagnostic vector; apply the error diagnostic vector to the healthy diagnostic vector to generate a ratio diagnostic vector; and apply the ratio diagnostic vector to generate a value for each failure mode.

Abstract: The disclosed embodiments may relate to a communication device (10). The communication device (10) includes an audio input device (26) that receives voice commands with at least one of the voice commands being an alphabetic character. The communication device (10) also includes memory (30) that is used to store the voice commands. In addition, the communication device (10) includes a control module (12) coupled to the audio input device (26) and the memory (30). The control module (12) associates the at least one of the voice commands with one numeric digit.
